Course Description

In-depth study of software design and implementation using a modern, object-oriented language with support for graphical user interfaces and complex data structures. Topics covered will be specifications, design patterns, and abstraction techniques, including typing, access control, inheritance, and polymorphism. Students will learn the proper engineering use of techniques such as information hiding, classes, objects, inheritance, exception handling, event-based systems, and concurrency.

This course is part of the Applied Computer Science Degree in Software Engineering as well as the Software Engineering Minor.

Course Materials

Note on the course materials: We'll start with Liskov. Don't worry about the publication date; Liskov is basically a math book, and hence ages remarkably well. We're interested in contracts, mutability, data abstraction, and type abstraction. Bloch is concerned about the same things, but explores them in more detail and in more up-to-date Java. Bloch also corrects some important points that weren't well understood when Liskov's text came out.

Course Outcomes

Weekly schedule

This class is a group-based, hybrid synchronous, online offering. That means you need to be present in class at class time. You will also need to schedule regular meetings with your group and with me (and possibly the GTA) outside of class.

This is my first offering of this class in a full-time online format. Some of what we will do is extracted directly from the F2F version of this class. Some of what we will do is new for the online offering. We'll keep what works and modify what doesn't.

Each week will cover a small number of related technical issues (see course schedule). Let's call this small number of technical issues a "topic". Each topic will follow roughly the same sequence of preparation, in-class learning activities, homework completion and (possibly) presentation, and knowledge assessment. To make this scale in an online environment, many of these activities will be group based. (See a later section in the syllabus on my view of the importance of interactive learning.) The sequence is:

Grading

Each of these grade components is discussed below.

Group Functioning

Every student needs to be part of a group. I would prefer that groups stay stable throughout the semester, but if there is a good rationale to reconfigure a group or two, we'll do that.

Group size: 2 to 4 students.

Group creation mechanism: As a default, we'll drop students into groups at random. If you are happy with your random group, great! If you prefer a different group, during the first week you will have the option to re-group. If your group dwindles to just yourself, you'll need to join another group.

At the end of the semester, each individual will provide an assessment of the rest of their group. This assessment will figure in to the "Group Functioning" part of the grade.

Groups can communicate internally through any mechanism they choose: zoom, discord, google docs, whatever.

Reading Quizzes

Each week, each group must complete a "reading quiz" the day before the first class of the week. (That means noon Monday, in the case of this class, since class meets Tuesday morning.) I will review these quizzes before class, compile the overall responses, and use them to tune the in-class activities. I plan to make these quizzes available on BB, but that might change if someone has a better idea. These quizzes are part of the learning process rather than the assessment process. That is, they generally don't assess whether you have achieved mastery of the material, rather they check whether you have done the necessary preparation.

Important: There are no make-ups.

Homework Assignments

There are weekly group homework assighments. I post homework assignments on the class web site. Generally, your group should submit assignments via Blackboard.

Because of the way in which this class is taught, it is important to stay on pace. Homeworks are due before class. Late submissions are not accepted except in truly exceptional circumstances.

Important: Each group should be prepared to present their homework solution in class.

Important: Statement of who did what. Homeworks are group exercises. Each submission must contain a specific statement of who did what.

Important: Solutions and solution checking. The group must split their roles on each exercise. Part of the group creates the solution. A separate part of the group checks the solution, certifies that it is correct, and explains why it is correct. If you can't formulate this explanation, it's time for your group to see me or the GTA in office hours. Note that this model is common in engineering, where engineers sometimes create solutions and other times certify solutions. You should rotate roles within your group from week to week.

Oral Assessments

Ideally, oral assessments happen every week. I am skeptical that I have the bandwidth to make that happen, but we'll try to get close. Realistically, each student should expect such an assessment every two weeks. Each student will have the same total number of oral assessments count towards their final grade.

Process:

Participation - Piazza Points

CS/SWE 332 will use the Piazza software for a discussion board and for posting updates. Participation on the discussion board counts towards your grade. Here's the deal: A constructive, relevant, non-redundant post earns a Piazza point. Here are some examples: You can earn one Piazza point, but no more, in any given week. (A "week" is defined as the way Piazza tracks weeks.) You're done earning points after you hit the magic number 5, but you are, of course, still welcome to continue posting. Participation must occur during the semester, not after final exams start. Note: starting early is good strategy.

I find anonymous discussions unhelpful in this class; here learning is predicated on interactions. Plus, part of your education is to learn to stand behind your questions and ideas. That's how employees function in the working world. Piazza allows partial, but not complete, control of anonymous posts. Should someone post anonymously, I will ask the poster to change the visibility and ask the class not to respond to the anonymous version.

Final Exam

There will be a final exam appropriate for the online, unproctored nature of this class offering. I plan to offer an oral option as well as a written option. The last class of the semester will include a detailed discussion of the exam structure and contents.

Class Attendance

I place great emphasis on peer learning and interactive engagement. Here's why. I have structured the class to leverage group interactions to the largest extent possible for the purpose of maximizing learning gain through out the semester.

Bottome line: It's important to be in class. This is reflected in the grade via the following formula: Two absences are "free". Each absence after that reduces the class attendance grade by 20%. The GTA will take attendance near the beginning of class each class meeting. (Note: I realize that there are connectivity issues. If this happens to you during a particular class, send a private message to the GTA as soon as possible. If this happens frequently, we need to talk.)


In-Class Exercises

I plan an in-class exercise for every class. Students will work in their designated group. Some of these exercises need a Java development environment. Very often, the in-class exercises will be closely related to an upcoming homework assignment.

ShowMe Videos/Other videos

The course schedule page links to a number of short videos created with the ShowMe service. Some students find these helpful for grasping key points from various lectures. Several items of note:
  1. Each ShowMe captures an interaction a student has with me. Such interactions can help students master the material more effectively than having me drone on solo.
  2. I am interested in creating more ShowMe videos for other topics in the course. Contact me if you would like to help me do this.
  3. I am open to redoing existing topics if there is something you think could be done better.
  4. Other videos are just me.

Record Keeping

We'll use Blackboard to maintain raw scores and attendance data. It's the student's responsibility to ensure that Blackboard records are correct. (I'm happy to correct errors.)

Email

Please note that questions of general interest should not be emailed to me. Post on Piazza instead.

Virginia Privacy Laws

The state of Virginia now has laws that require the University (including me) not to disclose student email addresses, phone numbers, and addresses. This will impact communications in this class as follows:

Honor Code

As with all GMU courses, CS/SWE 332 is governed by the GMU Honor Code. In this course, all oral assessments and the final exam carry with them an implicit statement that it is the sole work of the author. Further, all group submissions require a statement of participation from each member of the group.

Learning Disabilities

Students with learning disabilities (or other conditions documented with GMU Office of Disability Services) who need academic accommodations should see me and contact the Disability Resource Center (DRC) at (703)993-2474. I am more than happy to assist you, but all academic accommodations must be arranged through the DRC.
